Why SpaceX Faces a Longer Wait to Join the S&P 500 Index

​

June 5, 2026 — SpaceX's path to joining the S&P 500 has become longer after S&P Dow Jones Indices decided not to relax eligibility requirements for newly listed mega-cap companies, maintaining the current standards for inclusion in its benchmark indexes.

The decision means SpaceX, which is expected to begin trading on June 12, will not receive special treatment despite its massive size and anticipated valuation.

Earliest Possible Entry Is 2027

Because the company is expected to debut on public markets in June 2026, it would not be eligible for consideration before June 2027 at the earliest due to the minimum trading-history requirement.

Even then, the company would still need to meet the profitability and free-float criteria before it could be added to the index.

Profitability Requirement Remains a Challenge

Reuters reported that SpaceX recorded a net loss of $4.94 billion in 2025, despite revenue rising 33% to $18.67 billion. The company therefore does not currently meet the S&P 500's profitability requirement.

S&P rules require a company to report a profit in its most recent quarter and across the previous four quarters combined.

Limited Free Float Also Restricts Eligibility

Another hurdle is the company's relatively small public share float. Reuters calculations indicate SpaceX's free float is currently estimated at roughly 3% to 4%, well below the 10% minimum threshold required for S&P 500 inclusion.

Billions in Passive Fund Flows Delayed

Analysts had expected S&P 500 inclusion to generate substantial demand for SpaceX shares from passive investment funds. According to a J.P. Morgan estimate cited by Reuters, inclusion could have attracted approximately $10 billion in passive inflows under certain valuation assumptions.

While S&P has maintained its existing framework, rival index providers such as Nasdaq and FTSE Russell have adopted more flexible approaches, potentially allowing SpaceX to join some of their indexes sooner.
